Story
Sporty Spots is a very handsome Saint Bernard American Bulldog mix that weighs about 80 pounds! He absolutely loves people and loves to get attention and belly rubs! He will sit with his head in your lap getting all the head scratches for hours if you let him. He is a goofball and is sure to make you laugh and smile everyday.  Spots is a super friendly and outgoing dog. He is good with children that are aged 14 and over! He loves toys, and he also loves to play in water. He is the kind of dog that would love to play in the sprinklers and have his own little pool he can play in. He really loves to play with balls, he will chase them all day. Spots would do best in a home that has a backyard for him to run around in.  Spots does well with some dogs that are his size or larger. Spots will need to go to a home that has a strong handler and has owned large dogs before. So far, he has learned to sit, stay, and lay down.  Overall, Spots is an amazing dog that is waiting for his forever home. He is very loyal and very friendly with other people. He also is very protective of his home and loves to keep patrol of his yard! He loves toys and water and would make the perfect travel buddy!

Story
My brother-in-law dropped him off to us and never came back for him. We want to find a good family and home for him. We live in an apartment and we have his sister who is originally our dog. The space we have is just too small for two big dogs. He is a very good dog he just needs love and attention. We have tried our best to train him to the best of our abilities. We love him and want nothing but the best for him. But we never wanted two big dogs. We will do whatever it takes to find him a good home.

Story
We have had our 5 year old bully since birth, and she has done very well until she turned about 4. She tore both of her ACL’s and ended up needing multiple surgeries to repair them completely. She is now healed and as healthy as ever (up to date on all immunizations, medical appointments, heart guard, etc) and as playful as ever. Her issue now, however is that she has become extremely aggressive towards our older German shepherd that she has been around her entire life. We did everything we possible could to help her, including sending her to a very expensive boarding school for over a month. She is very obedient now and utilizes an E-Collar all the time and a muzzle when on walks. She still can not be around our other dog as even with the efforts and training, she still tries to attack him. We additionally have a 1 year old son in the home that Stella does amazing with. She is the biggest teddy bear with humans, is a huge goofball and has a good heart. She needs a responsible owner.

Story
Penny is a super affectionate sweet bulldog. She loves all people and she does get along with most dogs very well. She does the best when she meets new dogs in a home environment or in a yard. But she goes outside with about five other dogs everyday and never has an issue. She can be a little dominant so she probably wouldn't do best with another female that's very dominant and in your face. But mellow girls or boys she would be good with.

Story
LION – Male Boxer | 2 Years Old - DOB 11/25/2023 |    50 lbs | Healthy, Vaccinated & Neutered Introducing Lion, the sweetest big-hearted Boxer boy you’ll ever meet! At 2 years old, Lion has that perfect blend of Boxer goofiness and soulful loyalty. He’s playful, affectionate, expressive, and absolutely loves being near his humans. Lion is the type of dog who wiggles when he’s happy, leans in for cuddles, and charms everyone he meets with his warm, gentle nature. Breed Info: Boxers are known for their intelligence, athleticism, and famously silly personalities. They are deeply loyal, people-oriented, and incredibly loving companions. Boxers thrive on interaction, bonding, and being included in family life. Lion reflects the best of his breed — goofy, devoted, and full of heart. Owner Responsibilities: To help Lion thrive, he’ll need: Daily exercise (walks, play, and engagement) Structure, training, and positive reinforcement Plenty of affection and time with his family A safe, stable home where he won’t be left alone too long Give him routine, purpose, and love — and Lion will give you devotion for life. Things to Consider Before Adopting Lion: Are you ready for a medium-energy, highly social dog? Do you have the time and stability for daily exercise and bonding? Is your home and landlord dog-friendly? Are you prepared to commit to a dog for the next 10+ years? Are you ready for a dog who wants to be included as part of the family, always? Dogs are forever — not until convenient. Vet Care: Lion is healthy, vaccinated, and neutered. Please take him to your own vet shortly after adoption to set up ongoing care and ensure his continued well-being. The 3-3-3 Rule & Lifelong Commitment: First 3 days: He decompresses and starts to feel safe. First 3 weeks: Lion learns your routine, expectations, and begins trusting fully. First 3 months: He bonds deeply, understanding he is truly home at last. Adoption is forever — and Lion is ready to give his heart unconditionally. Why Lion Would Be a Great Addition: Lion is a loyal, affectionate, and joy-filled companion who will bring warmth and love into any home. His expressive Boxer charm, playful energy, and gentle nature make him the kind of dog who forms bonds that last a lifetime. He’ll make you laugh, comfort you on hard days, and love you with everything he has. He’s not just a dog — he’s family. &#226&#157&#164&#239&#184&#143   If you are interested in adopting this amazing dog, please follow the link https://www.ozzieandfriendsrescue.org/adoptions and fill out an application  Thank you for choosing Ozzie and Friends Rescue. We can’t wait to connect you with your new fur-ever friend. Ozzie and Friends Rescue makes arrangements for all dogs adopted to be transported all across the Western United States, Canada and the Midwest.January 21, 2026, 5:01 am

Story
******Please note, once completing the initial screen you will be connected with the placement for a video chat. Transports run every few weeks and we will have the dog on the next available transport once approved. If you are not able to accept a dog until a specific time period, please apply at that time************ We are a volunteer run rescue and donate our time to these dogs. IF you are not serious about moving forward in our adoption process, please do not apply. If someone other than yourself is part of the decision making process, please make sure you have spoken with them and they are on board. We really do not want to waste anyone's time if you are not serious about adopting this dog. Teeka, a 1 year 7 month old spayed female, Boxer mix, 42lbs. She is in a foster home in Houston, TX and can transport out of state once an approved adopter is lined up! The amazing Teeka is on the hunt for her forever home. She specializes in best friending with an emphasis on playing! She currently lives with several larger dogs and is learning to respect their boundaries. She LOVES to play with them, but does need some help realizing when her foster siblings are ready to stop. She has not met any cats, so we’re not sure how she’d react to a feline sibling. Her foster mom says she’s done well meeting new human friends and is learning not to jump on them. Because of this and her high energy levels, we do recommend a home with older dog savvy kids. This smartie is house and crate trained! She sleeps quietly in her crate and is kenneled whenever her foster family is out of the house. We don’t recommend leaving her out unsupervised as she may help herself to whatever she finds in the kitchen. Teeka’s love for food is next level and she will try to sneak a bite from you or the other dog’s bowls, but has shown no signs of resource guarding. She is still working on her leash manners, but is getting better every day! She gets a little too excited when she sees other dogs, but is learning to calm down and continue on her walk. This happy girl absolutely loves toys! She knows where the toy basket is and will get one so you can join in the fun. She’s a huge fan of fetch and tug of war! Teeka is learning the joys of relaxing too. She loves to lay on your legs and get some pets and give some kisses. She’s happy just to be near her humans. Teeka is a young pup with boundless energy that will thrive in a home with a yard, daily exercise, training and patience. She’s a goofy, happy, loving girl and with just one look into those pretty doe eyes, your heart will melt! ***Listed BREED and AGE - We are taking our best guess & recommendations from our veterinarian on age, breed and size when fully grown. We rarely know a dog's exact age nor are we able to tell the true or full breed mix of dogs as our information is limited most of the time. *** Interested in applying to adopt her?
